I followed some tutorials and created this system of bandwidth management to redistribute a specific percent of internet band to each computer.
My first question: is it correct?!
My second question: if it's correct, why these rules give me problems with local transfer of files? When I use this firewall and try to transfer a file from a pc to another pc of my local net, the maximum band is assumed to be that was defined in "bnd_downstream" and the rate can't be taller than "7168MB"...but it isn't correct: this value should be EXTERNAL DOWNLOAD BAND, not internal that is 1000MB/s (gigabit ethernet card). If I use the same firewall without this bandwidth management, but with the same other rules, local transfer goes well!
Where is the problem?! Thanks.

Oh...The problem seems to be in altq on internal interfaces ($int_if and $dmz_if) because if I comment these altq rules and all rules for bandwidth management on these nets, transfer rate is owkee...I also tried to change:

pass out on $int_if proto { tcp udp } from any to $host_usr1 queue dn_host1
